In his first-ever interview, the sole Australian survivor of the Waco siege has revealed to 60 Minutes what really took place during the 51-day stand-off, and why he believes crazed cult leader David Koresh will one day return to Earth as the son of God.

A convoy of 120 trucks has rolled into the NSW town of Cobar, as it makes its way to deliver 4500 square bales of hay to Queensland farmers whose properties and livestock have been ravaged by drought.

The Burrumbuttock Hay Runners, headed by NSW farmer Brendan Farrell and compromised of fellow NSW farmers and truck drivers, are now more than 390km into their mammoth 1860km journey to Ilfracombe, Queensland - where they’ll deliver the hay to more than 200 devastated properties.

The main convoy, which left Darlington Point at 6.30am today, stopped off in Cobar for a lunch break after nearly five hours on the road.

They were met by supporters who had gathered funds to provide them with snacks and refreshments, with some townspeople assembling on the main street to wave the trucks in.

Hauling more than 150 trailers full of hay and stretching roughly 50 kilometres, the convoy could even set a Guinness World Record.

"There are 138 trailers who have donated hay going that distance, there is no record of it being done before, so it will make a record," Mr Farrell told the Sydney Morning Herald.
